36VHigh-performance, High-reliability Withstand Voltage Stepping Motor Driver - BD63720AEFV

BD63720AEFV is a bipolar low-consumption driver that driven by PWM current. Rated power supply voltage of the device is 36 V, and rated output current is 2.0 A. CLK-IN driving mode is adopted for input interface, and excitation mode is corresponding to FULL STEP mode, HALF STEP mode (2 types) and QUARTER STEP mode via a built-in DAC. In terms of current decay, the FAST DECAY/SLOW DECAY ratio may be set without any limitation, and all available modes may be controlled in the most appropriate way. In addition, the power supply may be driven by one single system, which simplifies the design.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
